POLY ALUMINIUM CHLORIDE
Poly Aluminium chloride in all form, is extensively used as an industrial coagulant and Flocculent in different industries. Different grades of PAC are available for different purposes. PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro - organisms and colloidal particles, silt and clay are stabilized by Surface ELECTROSTATIC charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum.
